A dedicated server is an entire physical machine rented to one customer, so no other tenant shares its processor, memory, disks or network port.
Why it matters
Dedicated hardware gives predictable performance, no noisy neighbors and full control of the stack, including the choice of hypervisor, disk layout and security tooling. It suits large databases, high-traffic sites and workloads with compliance rules that discourage shared hosts.
The trade-off is cost and rigidity. Upgrading often means a hardware swap or migration, and a failed component can mean waiting for the provider's technician unless you have spares or a second machine.
Example
A company runs its main database on a dedicated server with 128 GB RAM and two mirrored NVMe drives. A second dedicated server in another rack replicates the data, so a failed power supply on the first does not cause an outage.
Common mistakes
- Running one dedicated server with no standby. It is powerful, but it is still a single point of failure.
- Overbuying capacity when a VPS or cloud instance would be enough and cheaper.
- Skipping out-of-band access such as IPMI, which makes recovery from a frozen machine slow.
